Problems solved by technology
In the sintering production process, people often treat the above parameters in isolation. When one of the above parameters changes, they always think that the physical and chemical quality indicators of the raw materials and fuels for sintering have changed, and ignore the relationship between various parameters in the sintering process. Therefore, it is difficult to find the real change factors in the sintering production process, and it is impossible to find out the change law of the parameters. The sintering process is chaotic, and the sintering production and quality are low.

Embodiment Construction
[0010] In order to effectively reduce the waste of air volume during the drafting process and make rational use of resources, the ash unloading system of the flue of the sintering machine was transformed, and a well-sealed cylinder type ash unloading valve was practiced and used to reduce air leakage. Gray to ensure smooth air flow. Renovate the material distribution system of the machine head, adjust the layout of loose material rods, increase material surface leveling plate and pressure roller, ensure the material surface is flat, ensure the uniform distribution of air flow in the sintering process, and create conditions for the mode operation of the main exhaust fan damper control. Through theoretical calculations and long-term practice summaries, the adjustment of the main exhaust door is controlled by a model, and the speed range of the sintering machine, the thickness of the material layer, the negative pressure and the opening range of the main exhaust door are reasonabl...

The present invention relates to a parameter matching and adjusting method of a sintering machine, which aims to improve sintering ore quality, reduce the power consumption of a main exhaust blower and reduce sintering inner circulating return fine rate. In the parameter matching and adjusting method of a sintering machine, a machine-head cloth system is rebuilt, the layout of loose metal rods is adjusted, and level flat material plates and nip rolls are increased. The opening degree of an air door of the main exhaust blower is controlled in modelization. The machine speed of the sintering machine, the machine-hour output and the opening degree of an air door of the main exhaust blower are reasonably matched. On the premise that sintering mixing material moister of 7.0% and sintering speed of 2.85 m / min are used as constants which are not changed, on the basis of the sintering mixing material layer of 710 mm, the optimal matching value of sintering channel subpressure and sintering terminal position parameters is adjusted. Under the condition of the sintering mixing material layer of 710 mm, the machine speed is stabilized at 2.85m / min. by that the sintering mixing material moister is every improved to 0.1%, the sintering firing temperature is improved to 16.5 DEG C, and the sintering terminal is averagely improved to 6.5 DEG C. Therefore, the present invention is favorable to control.
Description
Technical field [0001] The invention relates to a parameter matching adjustment method of a sintering machine. Background technique [0002] There are many parameters in the sintering production process, including the speed of the sintering machine, the opening of the damper of the main exhaust fan, the thickness of the material layer, the temperature of the sintering end point, the negative pressure of the air duct, the sintering ignition temperature, and the temperature of the exhaust gas. In the sintering production process, people often treat the above parameters in isolation. When one of the above parameters changes, they always think that the physical and chemical quality indicators of the raw materials and fuels for sintering have changed, and ignore the relationship between various parameters in the sintering process. Therefore, it is difficult to find the real change factors in the sintering production process, and it is impossible to find out the change law of the ...
